To. all rvhom it may concern Be it known that I, JONATHAN 0. FowLEn,

` Jr., of'New York, in the county of 4Newt-York 4carried by a jolting motion of the apparatus "in one direction by a series of short rapidlys'ucceeding'movements, and then automatically carried in an opposite direction in like manner. Miyf'apparatus differs therefrom in thatmy belt or apron is' advanced .by a succession of long lmovements separated from each other by considerable intervals off time, whereby each sign or placard is exposed for a considerable period of time and thenext then exposed by an instantaneous change.

Referring to the accompanying drawings,

Figure l represents a rear elevation of the apparatus; Fig. 2, an end eleigvation of the same; Fig.3, 'a horizontal section on the line x, Figs. l and 2,1ooking downward, the teeth of the cam-wheel being developed or shown in plane projection; Fig. 4, a vertical cross-section on the Vline y y, Fig. 3, developed or shown in a plane projection by dotted lines 5 Fig. 5, a view illustrating the. attachment ot' the pendulum by which the motion of the apparatus is'con trolled. 1

Referring to the drawings, A represents a rigid rectangular frame designed to support andhold the various operating parts. This frame is provided at its opposite front corners with two upright rolls, B, to which are attached the opposite ends of a vertical apron or belt,.0, the forward surface of which is provided with cards, signs, or advertising devices of any suitablecharacter. By means of mechanism hereinafter described the rolls are turned first in one direction and then in the other,thereby causing-the belt to move transversely first up on one roll and then upon the other, thereby displaying the various cards successively at the front of the apparatus. The mechanism by which motion is imparted to the 'rolls is clearly represented in the drawings. v

At the top oftheframe, in oneend, is'mounted au ordinary elocktrain, E, consisting of a train of gear-wheels'driven by means of a spring, G. The clock-train and spring, which may be of any ordinary or suitable construction, are provided with a winding-arbor, H, of ordinary construction. 'lhe last or terminal pinion I of the clock-train has its shaft provided with a crank, K, connected. by a pilman, L, to a crank-arm, M, attached to a rock -shaft, provided with a pendulum, N, the pendulum serving through the connections described to control the motion of the clock`tran andeause the same to run down slowly. Onl the main or winding arbor H ofthe clock-train I secure by a pawl and ratchet, or by any other eqiiivalent device which will permit the arbor to be turned independently, a sprocket-wheel, O, which is connected by a chain, P, with a corresponding wheel, Q, mounted on a horizontal shaft, R, in the base of the frame.. The shaft R carriesa large camwheel or drum, S, of the peculiar construction represented in the drawings. This wheel or drum is encircled by a series of inclined or beveled teeth, a and a', formed or secured thereon. Around one half of the circumference the teeth a are beveled or inclined to the right, but around the remaining half they are inclined to the left, as represented in Fig. 1,and also in Fig. 3. It will be seen that the bases or inner ends of the two series of teeth are in the same, or substantiallythesamc,circumferentialline,andthatthe two series extend right and left from this line, which,for the purpose ofconveniencc, l denominate the median line.77 At the point where the endsof the two series of teeth meetopenings b are left between them, as plainly represented in Figs. l and 3. These openings are made to permit the passage of a pin, T, operated by the teeth to the right and left of the median line,as hereinafter described. To facilitate the passage of the pin, one tooth adjacent to each opening b is rounded on the rear side, as shown at c, Fig. l.

.The pin T extends upward from a reciprocating block, U, which is sustained by rollers d,v

IOO

traveling on the base plate, and guided by means ot' two horizontal rods e, which are secured to the block and extended loosely through guides f, secured upon the baseplate. During one-halt of the revolution ot' cam-wheel S the teeth a act one after another against the pin T, forcing the pin, the block U, and the guide-rods c repeatedly toward the right hand, the pin and rods being moved gradually by each tooth tothe right of the median line until the pin passes the point of the same, whereupon the parts move backward quickly to the left to the base ofthe next tooth, this return movement being effected by means of a spring hereinafter described. As the cam-wheel S completes a halfrevolution, and the teeth a have all acted snc eessivel y upon the pin T, the opening b is brought opposite the pin, whereupon the pin passes through the same to the vlel't in position to be acted upon bythe teeth c', by which the pin and the rods connected therewith are repeatedly moved to the left, the pin now operat ing to 'the left of the median line. After the action vof each tooth a! the pin is returned to the base ot' the next tooth by a spring hereinafter described. As the cam-wheel completes the entire revolution the pin, vreaching the end ot' the series of teeth a', passes through the second opening, b, to the right, where it is again acted upon by the first series of teeth a, as before described. It will thus be seen that by the continuous rotation of the cam-wheel the pin andthe connected parts are first moved by a series of vibrations to the right of the median line, and then given a like series of vibrations to the left 5f the median line, and so on alternately and repeatedly, this action oceurring many times while the clock-train is running down.

The springs by which the reciprocating rods are thrown to the right when under the action of one set of teeth, and then thrown to theleft when under the action of thesecond set of teeth, are clearly represen ted in Figs. 1,3,and 4. Two horizontal arms, W and W', are pivoted to the base-plate and connected respectively with independent spiral springs a' and .00',attached to fixed studs on the base-plate, the springs acting to throw the ends ot' the arms W toward each other. The movement of the spring-driven arms toward each other is limited by means of a fixed bar or stop-plate, Y, against the ends ot' which the arms come in contact. The two arms and springs operate alternately. The rods e are provided on the back with two shoulders, Z Z', as shown in Fig. 3, to engage with the ends of the spring-arms. During the action of the teeth a, when the 'parts are driven toward the right, the projection Z' ot' the rackbar encounters the arm W' and forces the same to the righot, and as each of the teeth a 'ceases its action the said arm forces the rods to the left. During this action the arm W rests against the stop plate Y and is inactive. When, however, the teeth a' are brought into action so as to move the rod to the left, 'the stud Z of the rack-bar encounters the spring-arm NV, forcing the same to the letr t, so that the arm drives the rod back to the right as each ot teeth a ceases its action. During this operation the arm W' rests passively against the end ot' the stop Y.

To the reciproeatin g guide-rods e, I secure a horizontal rack-bar, V, which is carried by the movements ot the bar first repeatedly to the right of a central line and then repeatedly to the left ot' said line. The rack-baris designed to operate upon two wheels, A' and B', alternately, the wheels being located, as shown in Fig. 3,.tn such position lthat when the rack-bar is driven to the right by cam-teeth a it will operate upon the wheel B', being carried away from the wheel A', and that as the bar is moved to thelet't by the action ofthe teeth a.' t-he'bar will l"operate upon the wheel A', being carried out of contact with the wheel B'. The wheels A' and B' have a pawl-and-ratchet connection, as shown, with large gear-wheels C' and D', respectively, these wheels both gearing into a third wheei,.E'. The wheel E' is attached to the `axis vot' a large double pulley, F', which is connected by two belts, G' and H', with pulleys on thelower ends of the apron-carrying rolls B, for the purpose ot' turning the said rolls.

As shown in the drawings, the ratchet-teeth ot' theI respective wheels are faced in such directions that during the time the rack-bar is being operated to the right by the calnteeth ait turns the gearing in such manner as to move the apron to the left, and that as the rack-bar is moved to the left by the action ot' the cam-teeth c' it causes the apron to move to the right. In this way the continuouslyrevolving cam-wheel causes the apron to move first to the right and then to the left. The ratchet-connection may be such that a positive motion will be imparted from the eamteet'h to the rolls; but itis preferred to face the teeth in the opposite direction, as represented in the drawings, so that during the time that the rack-'bar is being gradually moved by the `cam-teeth the apron and its driving-gear will remain at rest. Under this arrangement the movement of'the rolls and the driving-gear connected immediately therewith is effected by the rack-bar during the time that the latteris being moved or returned under the action ot' the springs w fr'. This arrangement is preferred for the reason that it permits each card or advertisment to remain at rest and exposed to view7 for a period of time, and then causes the apron to be moved quickly to expose the next card. A

While it is preferred to retain substantially the 'constructionrepresented in the drawings, it is obvious that the minor details et' the apparatus may be varied in form orl arrangement, provided there is no essential departure from the mode of action described and shown.

Having thus described my invention, what I claim is r1. The combination of the apron C, adapted to move on the supporting-rolls B, the clocktrain, and the intermediate mechanism, sub

IOO

stantially as described,whereby the clock-train is adapted to canse the apron to advance byT a series of quick movements, with long intervals of rest, in one direction, and then in like manner inthe opposite direction, whereby the cards or signs are displayedsuccessivelyand one changed instantly to expose another.
